IMPROVEMENT lN BUCKLE ATTACHMENTS FOR ELASTIC BANDS 0R STRAPS.

Specification forming-part of Letters Patent No. 188,330, dated March13, 1877; application filed I February9, 1877.

To all whom it may concern:

Be it known that I, FRANK ARMSTRONG, of Bridgeport, in the county ofFairfield and State of Connecticut, have invented certain new and usefulImprovements in Elastic Adjustable Straps; and I do hereby declare thatthe following is a full and exact description thereof, reference beinghad to the accompanying drawings, making a part of this specification.

My invention relates to certain improvements in elastic metallicadjusting-straps. It has for its object to provide a simple and durablemeans of securing the ends of metallic coils forming the straps to thebuckles or loops; and consists in forming. that portion of the buckle orloop which enters the coils with slots or openings, to receive asecuring needle or pin, as will be hereinafter more fully set forth.

Previous to my present invention it has been customary to secure thecoils to the.

buckle or band in one or the other of two.

ways, either by turning over the ends of the penetrating-shanks to forma hook, and then passing through the same and the coils a securing-pin,as shown in Letters Patent No. 145,160, dated December 2, 1873, or byforming that'portion of the buckle or loop which enters the coils with a'hook on one edge of each shank, asv shown and' described in LettersPatent No. 109,737, dated November 29, 1870.

The disadvantage attending the former construction rests in theliabilityof the hooked ends of the shanks being drawn or straightened out whenthe band is stretched, resulting in the disconnection of the coils fromthe loop or buckle, and also the further disadvantage of difficulty andexpense of manufacture of the hook-shanks; and the disadvantage of theconstruction shown and described in the latter Letters Patent consistsin the liability of disengagement of the booksfrom the coils, resulting,in a measure, from the fact that the hooks are secured directly to onlyone side of the coils.

My present invention overcomes all of these I objections, and rendersthe connection between the buckle and bandssimple, economic, anddurable. Y

To enable others skilled to more readily'understand' my invention, Iwill describe the same, referring by letters to the accompanyingdrawing, in which' Figure 1 is a plan vi with double buckle securedaccording to my invention. Fig. 2 is a similar view broken away at ornear the'center, and with the concealing or finishing cap removed, andexposing the method of securing the parts together. Fig. 3 is a "erticalsection at theline a; w of Fig. 1; and Fig. 4 is a plan view of thebuckle, showing more fully the enteringshanks by which the same issecured to the coils. .Similar letters indicate like parts in theseveral figures. v

-A represents the coils'torming'the elastic band, and B B the buckles orbuckle and loop, as desired. 0 O are metallic finishingcaps, which arepressed in place, forming a finish to and concealment of the connectionbetween the buckles and band. The buckle.

or loops A are formed with projecting shanks stretched or distorted inopposite directions,

as illustrated by the shade-lines at 'Fig. 4, and in section at Fig. 3.

This construction may readily be eifected at one and the same operationwith the stamping out and formation of the buckle-blank.

The shanks D, having been formed with the slots at therein, are insertedwithin the ends of the several strands of coiled wire forming the band,and a pin, F, is passed between the coils of the several strands, andthrough the slots. or eyes a in the shanks D, thus firmly securing theparts together, as clearly seen at Fig. 2.

After the parts have been thus secured,

the well-known finishing and concealing caps O are secured in position,and the structure is complete.

What I claim as new, and desire to secure by Letters Patent, is-- i Inelastic adjusting-straps, the buckle or ew of an elasticband,

said shanks being provided with eyesyand having the surrounding metaldistorted in opposite directions, as described, to receive thesecuringpin, substantially as set forth.

In testimony whereof I have signed my FRANK ARMSTRONG. 1. s]
